GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 269,008, dated December 12, 1882; l

Application filed June 10, 1882. (ModeL) gangplows; and it consists, first, in the combination of a rack-bar or standard, which is secured to the top of the axle, suitable straps, which extend from the plow-frame up over the top of the rack-back, and a toothed quadrant, which meshes with the standard, and an operating lever or spring, whereby the plowframe can be raised and lowered and held in any desired position; second, in the combination, with the plow-frame, of suitable guidingrods which pass up through the axle, and suitable means for raising and lowering the plowframe, all of which will be more fully described hereinafter. t

Figure l is a side elevation of my invention. Fig. Z is a plan view. Fig. 3 is arear view partly in section.

Arepresents adriving-wheel, and B a straight axle. Secured to the under side of each end of this axle is the slotted casting 0, through which is passed a suitable clamping screw or bolt, D, for holding the casting E, carrying the spindle F, in any desired position. This casting has suitable flanges or projections formed on its inner side, so as to catch in the slot that is made in the castings on the axle, and thus hold the casting E always in posi tion. Formed on the outer side of each casting E is a rim or flange, F, which serves as a dust-band for the protection of the spindle. By adjusting the castings E up and down the depth of the furrows can be regulated at will. The plow-frame consists of three beams, G, which are of different lengths, and which are secured rigidly together at their front ends by meansofthecross-barH,andtheirrearends are connected together by means ofthe bent plates I. The tongue J is pivoted to the frame at Figs. 4 and 5 are detail views.

its rear end, and can be adjusted at its outer end by means of the perforated guides K, so as to turn the points of the plow downward to any desired extent. Secured 'to each side of this plow-frame is a rod, L, which passes up through the axle and through suitable guidin g-castings M, which are secured upon the top and under side of the axle. These castings serve to prevent the axle from being worn, and to form longer bearings for the rods, so that they are not likely to become bentand twisted from the strain that is brought to bear upon them.

Secured to the top of the axleis the toothed standard or rack bar 0, with which the toothed quadrant P engages, for the purpose of raising and lowering the plow-frame. This quadrant is journaled in the metallic frameQ, which passes up over top of the standard and the top of the axle, as shown. This metallic frame consists of two metallic plates, which are united together at their lower ends, and which are soshaped as to be sprung slightly apart at their centers to allow the toothed standard to pass up in between them. The toothed quadrant is journaled in this metallic frame upon a rod which passes through, the frame, the quadrant and the end of the operatinglever R, which has a spring, S, applied to one of its'ends, so as to keep the frame closed against the side of the standard and the quadrant. One side of the quadrantis recessed,'so as to allow the end of the lever to be applied thereto without increasing the thickness of the two parts.

Secured to the inner side of the frame, just opposite the vertical row of perforations which is made through the standard, is a suitable catch or projection, T, which, when the frame sired. As soon as the frame has reached the desired point the lever is released, when the force of the spring will at once cause the frame to close and the catch to snap into one of the holes in the standard.

It will be seen that the plow-frame is braced against all lateral strain or movement of any kind by means of the two rods which pass up through the axle, and the frame, which passes over the top of the standard.

Having thus described my invention, I claim 1. In a gang-plow, the combination of the axle B, having the slotted castings G, secured to each end, the castings E, having flanges or projections to catch in the slot, and a dustband, F, upon its outer side, the castings E having the spindle F formed as a part of it, and being held in any desired position by means of the set-screw D, substantially as shown.

2. The combination of the plow-beam, provided with a guiding-rod, L, upon each side,

the axle, and suitable guiding-castings, M, se-

cured upon the axle, substantially as described. 3. The combination of the plow-frame, the metallic frame secured thereto, the toothed standard, the quadrant having a lever secured to it, a springfor closing the frame, and a catch to snap into the holes in the side of the standard, substantially as set forth.

4. The combination of the plow-frame, the frame Q, made in two parts, the spring for forcing the parts together,tlie perforated standard, and elevating lever, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES D. CARTER.
